memory + server SAS hard disk. 2. I personally think that Intel's CPU in the server CPU field is better than AMD's CPU. If there is any objection, I will say that I am so arrogant (please refer to the CPU performance comparison ), do not trust AMD's advertisement too much. A simple way to compare CPU performance is to compare the price. Do not compare the frequency with the number of cores, and the price is similar to the performance. 3. Hard Disk pe

Iops(Input/output per second) is the input output per second (or read/write count), which is one of the main indicators to measure disk performance. Iops refers to the number of I/O requests that the system can process per second, i/O requests are generally read or write data operation requests. For applications with frequent random reads and writes, such as OLTP (online transaction processing), iops is a key indicator. Another important indicator isData throughput(Throughput) refers to the amou

Because SAS is installed in the "Windows Authentication Mode" mode by default during installation, SAS logon is disabled.If you change the Authentication Mode to "SQL Server and Windows Authentication Mode",

). Obviously, MLC has a larger storage capacity than SLC, but SLC is simpler and more reliable, SLC reads and writes faster than MLC, and SLC is more durable than MLC, MLC can be erased for 1 million times per unit, while SLC can be wiped for 10 million times. Therefore, enterprise-level flash storage products generally use SLC, Which is why enterprise-level products are much more expensive than home products. Technical Features of SSD SSD, compared with traditional disks, has no mechanical dev

materials. Hard drives are solid-state drives (SSD disks, new hard drives), mechanical hard drives (HDD legacy HDD), Hybrid drives (HHD a new hard drive based on traditional mechanical hard drives). SSDs are stored using flash particles, HDDs are stored with magnetic discs, and hybrid drives (Hhd:hybrid hard disk) are a hard disk that integrates magnetic hard disks and flash memory. Most hard drives are fixed hard disks that are permanently sealed and pinned to the hard drive. The disks in the

One, the following is my test results: For the speed limit of 100m below, in fact, the type of hard disk and read and write speed has no effect, but how to limit the speed of more than 150m, or infinite speed, then the hard drive is definitely ssd>sas>sata, so it is recommended to use the SAS disk as a Docker mount partition.Openvswitch The default official document provides a speed limit method "rate li

transmission instruction (not only the data) to examine, if discovers the error will automatically correct, this greatly enhances the data transmission reliability. The serial interface also has the advantages of simple structure and hot-swappable support. SATA2 Seagate joins the NCQ Local command array technology based on SATA and increases the disk speed. SCSI is known as the small Computer system Interface (minicomputer systems Interface), after many generations of development, from early

What are the data warehousing solution software available for selection in the market? What difference does it have? Can you analyze and compare their performance and characteristics? Powerful companies such as IBM, Oracle, Sybase, CA, NCR, Informix, Microsoft, and SAS have launched their own data warehousing solutions (through acquisitions or research and development). Professional software companies such as Bo and Brio also have a place in the fron
